Woman wondering why her AC is acting up

Why does it smell bad when my air conditioner runs?

The majority of us install air conditioners to help us feel relaxed in our homes. But when you start to experience unpleasant odors coming from your cooling system, it’s more than just annoying. It can greatly impact your home comfort.

Where do the smells come from?

Focus on what the odor smells like. If the odor resembles a rotten egg, this could be a indication of a gas leak. If this is the case, you should open your windows, turn off the gas supply, evacuate the home and contact the gas company. Be sure to have the gas company turn it back on for you. It’s not something you want to mess around with.

If it doesn’t smell like rotten eggs, you are likely experiencing a different challenge.

Just like anything in your home, if your air conditioner isn’t cleaned properly or taken care of, there’s a good chance that dirt and dust will gather. And because components of your air conditioner aren’t front and center, cleaning them can often go overlooked.

Buildup of mold, dirt and other particles is one of the most request reasons you’ll notice odors with air conditioners. It can happen with the coils, drain pain, air ducts or even your filter. However, regular maintenance can help prevent this buildup and reduce the odds that an unfriendly smell starts diffusing throughout your house.

Heat and moisture can contribute to increased mold growth, especially in warmer climates. Not only can mold and mildew induce a nasty smell, but it can also negatively impact the quality of air in your house.

It’s also possible that a tiny creature navigated into your duct system and died. You can turn off your air conditioner and either give our team or pest control a call to come and retrieve the animal.

What can I do?

Analyze your filter. This is a common culprit for air conditioner odors. If it’s been a long time since you’ve exchanged your air filter, go ahead and replace it with a brand new one. We typically suggest changing your filter every three months. But it’s also vital to keep in mind other factors that would require you to replace it more frequently, such as pets in the home or if a family member has allergies or asthma.

If you’ve replaced the filter and it’s not reducing the smell, it’s probably time to reach out for some help. Especially if it’s been an long period of time since your last air conditioning checkup. The pros can examine the situation to see if a thorough cleaning can do the job. You might consider having your air ducts cleaned. Professional duct cleaners can take a look to see if your indoor air quality would be enhanced from a proper cleaning.
